I need an AI-driven chatbot that lives on my website and acts as a round-the-clock technical support assistant. Its sole focus is to give visitors clear, accurate troubleshooting guidance and other tech-related answers—no upselling, no marketing talk. Here is what I expect: • A conversational interface that greets users, identifies their issue, and walks them through fixes or next steps based on our existing knowledge base. • Natural-language understanding so the bot can handle free-form questions and still surface the right solution articles or step-by-step instructions. • Seamless web integration: it must load quickly, respect our site’s branding, and work on both desktop and mobile browsers. • A simple back-end panel or API hooks that let me update FAQs, add new troubleshooting flows, and view analytics on user interactions. • Handover logic for the rare occasions the bot can’t resolve an issue, routing the visitor to a live agent or ticket form. I’ll supply current documentation, common error logs, and any product manuals you need for training. Once deployed, I’d like a brief hand-off session so I understand how to retrain or expand the model as new product versions roll out. Let me know which NLP stack or chatbot framework you prefer and your estimated timeline from setup to live launch.
